core: fix background not blurred under transparent windows
When a window has 0 opacity, it's rendering is skipped completely. Thus
its background isn't blurred.

This commit fixes that.

Preparation for dummy backends
Dummy backends are backends that doesn't render anything on to the
screen or the target window. But they are still be useful for debug
purposes, and can be useful for other things too.

render: don't free blur_kerns_cache when it's not used
blur_kernel_count could be none zero when user set a blur kernel but
didn't enable blur. In that case deinit_render will try to free
elements of blur_kerns_cache, causing a segfault because
blur_kerns_cache is never allocated.

Improve transparency detection for blur
Previously, only the WM windows (window manager usually reparents the
application windows under its own window so it can manage them) are
checked for alpha channels. Some of the window managers (e.g. awesome)
acquire alpha channels for all of the WM windows, whether the underlying
application windows have alpha channel or not.

With this change, the application windows are also checked for alpha
channels. If a WM window has alpha but its child doesn't, only the WM
frame will be considered to be semi-transparent. Thus preventing some
unnecessary blurring.

x: add x_discard_events
Also, during session_init, discard old events after we grab the server.
If we don't do that, old, out dated CreateNotify will cause us to add
the window with the same id multiple times. Here is an explanation of
how that could happen:

1. compton connects to X
2. a new window created by someone else, X send us a CreateNotify
3. compton is initializing, so it didn't handle the event.
4. compton pulls a list of all windows from X. This will include that
   window created in (2)
5. compton starts to handle event. it will handle the CreateNotify sent
   in (2), thus adds the same window twice.

win: split struct win
Currently compton handles window creation event by immediately query all

In the future, we want to react to window creation event by creating a
placeholder in the window stack, and only query window information in a
critical section where the X server is grabbed by us.

This commit split struct win into two struct, one as placeholder, the
other for holding actual window information.

When destroying window `w`, we need to invalidate all reg_ignore beneath

false`, we also need to invalidate `w->next->reg_ignore`.

Yes, this variable name is confusing. Will be changed in the future.

paint_preprocess calls redir_start if it decides to redirect the screen.
redir_start might change the state of the windows. For example, when the
image of the window fails to bind, redir_start sets the error flag. And
those state changes might exclude the window from being rendered. Thus,
paint_preprocess should be re-run to make sure the new states are
honoured.

Fixes a crash when window images fail to bind after redirecting.

core: don't use stale window images
Previously, when the backend doesn't implement root_change(), we will
deinit, and then init the backend again. However, we didn't free all the
images previously returned by the backend. There is no guarantee that
these images will be valid across deinit/init.

So, make sure they are freed.

win: release window image before rebind
Previously we try to keep the image data until the rebind succeeds. This
way even if the rebind fails, we still have something to display.

But that triggers a NVIDIA driver bug. Basically you cannot have more
than one names (XIDs) of a window pixmap. NVIDIA driver doesn't like
that, and binding the pixmap with its aliases will fail. This can
sometimes happen if we name the new pixmap before freeing the old one during
rebind, and the pixmap doesn't actually change (i.e. the rebind is
unnecessary, could happen because of X event handling complications).

Deprecate --glx-swap-method
Setting glx-swap-method to value other than "undefined" and "buffer-age"
could potentially cause rendering problems. So remove them, the meaning
of the remaining options can be more precisely captured by "use-damage",
so create a new option under that name.

--glx-swap-method is deprecated in favor of the new option --use-damage.
